Microfluidic investigation of pore-size dependency of barite nucleation

open access: yesCommunications Chemistry, 2023
Mineral precipitation in porous media is relevant for various energy-related applications such as oil extraction, geothermal systems, or nuclear waste disposal, but crystallization retardation as a function of pore size and shape is poorly explored. Here,

Selenite and Selenate Sequestration during Coprecipitation with Barite: Insights from Mineralization Processes of Adsorption, Nucleation, and Growth.

open access: yesEnvironmental Science and Technology, 2022
Coprecipitation of selenium oxyanions with barite is a facile way to sequester Se in the environments. However, the chemical composition of Se-barite coprecipitates usually deviates from that predicted from thermodynamic calculations.

The Formation of Highly Positive δ34S Values in Late Devonian Mudstones: Microscale Analysis of Pyrite (δ34S) and Barite (δ34S, δ18O) in the Canol Formation (Selwyn Basin, Canada)

open access: yesFrontiers in Earth Science, 2022
The sulfur isotope composition of pyrite in marine sedimentary rocks is often difficult to interpret due to a lack of precise isotopic constraints for coeval sulfate.

Marcasite at the Permian‐Triassic Transition

open access: yesGeophysical Monograph Series, Page 377-399., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
